Abstract
Dual inverter fed open-end 3O induction motor drive (OEW-IMD) with different dc-link voltages can perform four-level (4L) realisation. Now the earlier scheme operates with high conduction losses and dv/dt at particular voltage symmetries that effects overall efficiency. This paper proposes the effective discontinuous decoupled SVPWM (EDDPWM) scheme, which deals the DD-PWM with a concept of effective time employment to high voltage side inverter and low voltage side inverter independently that are labelled as EDDPWM-1 and EDDPWM-2, respectively. A factor variable k relating to active time of vectors application is presented. For k is varied from 10% to 100% of individual inverters that effects both individual and net inverter voltage vectors of a dual inverter. Therefore, the effect of factor k on ripple content, harmonic spectra of motor currents for insight of torque ripple, and different characteristics are analysed. These proposed methods achieved flexible performance enhancement compared to previous methods.
